[glibmm] GTlsDatabase: Use std::string for filenames.

[Murray Cumming <murrayc src gnome org>]

commit 773ada2f84c5c8b4da03794564fb9dd4d173cc65
Author: Murray Cumming <murrayc murrayc com>
Date:   Tue Mar 26 11:27:06 2013 +0100

    GTlsDatabase: Use std::string for filenames.
    
    * gio/src/tlsdatabase.hg: The anchor parameter
    and property are for a filename, so we should use
    std::string, because filenames are of unknown
    encoding.
